[Trans. Ext. Metro Tower roof; Sunset]

EFFY: A shame our brethren didn't survive the prison dimension. Then, again, their weakness has no place in my new empire. Open and bring unto this world the mighty power of EFFY!

(EFFT places the Key into the slot and New York City's power dies. Energy travels back up the growth to the Key. The Key fires energy into the sky, causing its portal open as the Technodrome emerges from it.)

Radio: Alberta—Warning! This is a warning [indistinct] appears to be something falling from the sk—

(Civilians flee as objects begin to levitate and asphalt is ripped from the ground by the Key portal as the Technodrome wraps its tentacles around Metro Tower.)

(EFFY, EEBEE, and OOTER climb a ramp and Cody kneels. EFFY, EEBEE, and OOTER each don their Titans.)

EFFY: Begin!

[Trans. Ext. New York City]

(Buildings and bridges fall as the Technodrome releases Metro Tower and pushes itself higher in the sky. The Technodrome releases projectiles from itself into the city, turning vehicles into zombies. The vehicle zombies attack and kill the military soldiers and fire sweeps New York City. The military fires several missiles at the Technodrome, but they are all destroyed by the Technodrome's laser before they can strike. Jeffy, Janice, Penelope, Junior, Joseph, and Chef Pee Pee watch the situation from a rooftop.)

Jeffy: What do we do now? 

Chef Pee Pee: [crestfallen] I fear we are lost. The Krang are too powerful.

Joseph: Maybe we could change the future some other way.

Janice: Guys, it's time to face facts. We can't change the future.

Joseph: Says who?

Penelope: Says the grandfather paradox, says physical determinism, says the space time continuum. Look, I didn't want it to be true but... says science.

Junior: That's it! Penelope's wrong!

Penelope: The world is ending, yet the barbs continue.

Junior: Don't you remember? We already did change the future. Cody never got kidnapped and turned into a zombie in your time. Right, Janice?

Janice: No, he didn't.

Junior: That means we did change the future! We're just in a different, uh...

Penelope: Bifurcated time branch!

Junior: Yes, yes, yes, that nerd thing. You know what that means, right? We still have hope!

Janice: A ninja's greatest weapon.

Junior: Hey, I like that! Look, I'm done thinking I have all the answers. I don't know how to beat EFFY, but I do know our future isn't written until we write it as a team. So, what do we got?

Jeffy: Maybe... maybe we don't have to beat them. Can't we just send them back to the prison dimension?

Junior: There's an idea! Penelope, what does that big, beautiful brain of yours have to say?

Penelope: If we got control of their ship, we could send it back to the portal.

Junior: Yes! Yes! Now we're cooking. Who else?

Janice: If someone on the ground can get to that Key...

Chef Pee Pee: We can close the doorway!

Joseph: And then bye-bye EFFY forever, baby!

Junior: Exactly. What do you say, Penelope? You ready to fly a spaceship?

Penelope: Literally the greatest question I have ever been asked.

Junior: All right, team, looks like we have a plan. Let's go save the world.

Joseph: Wait, but what about Cody?

[Everyone felt the same way, but Junior put a hand on his little brother's shoulder.]

Junior: That big nerd may be covered in goo and half-alien, but he's still our brother. He never gave up on us and I'm not giving up on him. I'm not leaving him behind.

(Subway bus zombies and helicopter zombies attack civilians. A helicopter  zombie aims its missiles at civilians in a coffee shop, but is suddenly destroyed. Another helicopter zombie fires missiles at Jeffy, Janice, and Chef Pee Pee but they are evaded and Janice grabs a missile with her grappling line, redirecting it into the helicopter zombie. Janice points to Metro Tower.)

Janice: There's the Key! Let's go.

(Something bursts through a skyscraper and launches itself at Jeffy, Janice, and Chef Pee Pee, knocking them onto the street. It is revealed to be EEBEE wearing her Titan.)

Jeffy: Like Janice said, let's go!

(Jeffy's team charges at EFFY and she prepares to punch them. Junior's team climbs the levitating rubble up to the Technodrome.)

Penelope: I wish my tech was working! Usually my cardio is jetpack-assisted. Oh, and I'm not getting credit for any of these steps!

(Penelope, Junior, and Joseph leap down onto the Technodrome. Junior penetrates its membrane with his katana and they fall inside.)
